Troubleshooting
Problem Cause Solution
My touchpad won’t power
on.
The touchpad is not
connected to a PoE switch.
• Connect the touchpad to a
switch that supports 802.3at
PoE.
• If a PoE switch is not
available, use a PoE injector
(sold separately) to power
the unit.
My touchpad isn’t receiving
an IP.
The connected network is
not DHCP enabled.
• Swipe from the left corner
to the right and press
the refresh button. It can
sometimes take up to 60
seconds to obtain an IP.
• Set the touchpad to static IP
by selecting the Set Static
IP slider and providing IP,
subnet, gateway, and DNS
server information.
